Physiology
Answer: 1) Induction of glucokinase
Explanation: Insulin enhances glucose uptake in the liver by inducing the synthesis of glucokinase, an enzyme that converts glucose into glucose-6-phosphate. This "glucose trapping" mechanism keeps intracellular glucose levels low and promotes further glucose entry into the cell.

Oral PathologyRadiographic resolution of a periapical lesion (an area of bone loss around the tooth root caused by infection) after proper root canal treatment typically takes time because it involves the biological process of new bone formation to replace the damaged area. This healing process is a gradual one, and while clinical symptoms resolve quickly, visible changes on an X-ray (radiographic resolution) can take several months to become apparent. The 6-12 month timeframe is the established period for significant or complete radiographic evidence of healing in most cases. A longer follow-up period may be needed in some instances.

For caries prevention, a 0.2% sodium fluoride mouth rinse is
typically recommended for use once weekly. This regimen provides sufficient
fluoride exposure to strengthen tooth enamel without causing adverse effects.

EndodonticsWhen performing vital tooth bleaching, local anesthesia is NOT routinely used because: 1) The procedure is generally painless, 2) Most patients experience only mild sensitivity which is manageable, 3) Anesthesia can interfere with patient feedback regarding sensitivity. Essential procedures include: prophylaxis to remove debris, protective eyewear for both patient and operator due to strong oxidizing agents, and polishing after treatment to smooth any etched enamel surfaces.

Oral lichen planus is a T-cell mediated autoimmune disease. IFN-γ and TNF-α are present in lesions and involved in its pathogenesis. IFN-γ is the key cytokine in cellular immune response.

PhysiologyCalcium is absorbed mainly in the duodenum and jejunum by an active transport mechanism regulated by 1,25 (OH)2 D3 (calcitriol). It is transported across the brush border of intestinal epithelial cells via TRPV6 channels and binds to calbindin. The absorbed calcium is then delivered to the basolateral membrane by calbindin, and from there it is transported into the bloodstream by either the sodium-calcium exchanger (NCX) or calcium-dependent ATPase.
